Efficiency of a Braking Process Evaluating the Roughness of Road Surface

Abstract: Transport traffic safety depends on many factors; one of them being the efficiency of the vehicle braking. The efficiency of the vehicle depends on the reaction of the driver, the braking system, the quality of tires, the characteristics of the road surface. The vehicle with the hydraulic braking system and a disc brake with the wheel has been investigated. The dynamic models of the disk brake assembly and the wheel have been constructed. The braking distances of the vehicle with a hydraulic ABS on the asphalt concrete pavement with shortwave roughness and different initial velocity are obtained. Language: en

A study of novel regenerative braking system based on supercapacitor for electric vehicle driven by in-wheel motors

Abstract: Taking supercapacitor and battery pack as the energy storage unit, a novel type of regenerative braking system for electric vehicle driven by in-wheel motors is presented, and a braking energy regeneration control strategy is set up. Then, a co-simulation test based on CRUISE and Simulink is conducted. The results of simulation show that the novel type of system can ensure the safety of battery pack and significantly improve the rate of energy regeneration.

Structural optimization of a circumferential friction disk brake with consideration of thermoelastic instability

Abstract: This research suggests a new disk brake design using circumferential friction on the disk of a front-wheel-drive passenger car. The paper compares mechanical performance between the conventional and suggested disk brakes under dynamic braking conditions. Thermoelastic instability is considered in simulation of the test condition. An optimization technique using a metamodel is introduced to minimize the weight of the suggested disk brake. To achieve this goal, the response defined in the optimization formulation is expressed in a mathematically explicit form with respect to the design variables by using a kriging surrogate model, resulting in a simple optimization problem. Then, the simulated annealing algorithm is utilized to find the global optimum. The design results obtained by the kriging method are compared with those obtained from ANSYS analysis.

System and method for managing hybrid vehicle regenerative braking

Abstract: A vehicle includes a powertrain having an electric machine configured to selectively apply regenerative braking torque to decelerate the vehicle. The vehicle also includes a controller programmed to control a rate of change of a regenerative braking torque limit during a transmission downshift that occurs during a regenerative braking event based on a change in speed of an output shaft of the powertrain caused by the transmission downshift.
